SUCTION-ROLL FOR PAPER-MAKING -MAGHINES.

- Application filed luly ll, 1910. Serial No. 571,356.

To all whom it may concern:

Be it known that we, JOHN F. KING and JAMES NEARY, citizens of the United States, residing at Kalamazoo, Michi an, have invented certain new and use ul Improvements in Suction-Rolls for Paper-Making Machines, of which the following is a specification.

This invention relates to improvements in suction rolls for paper making machines.

Our improved suction rollis particularly designed by us for use as a suction box, al: though it may be readily adapted and is desirable for use as a suction web forming roll for paper making machines.

The main objects of our invention are: First, to provide unimproved suction roll for lpaper making machlnes which may be quic ly adjusted to webs of the desired width while the roll is revolving. Second, to provide an improved suction roll for paper making machines, which is compare tively. simple in structure and, at the same time, very efl'ective for the purpose.

Further objects, and objects relating to structural details, will definitely appear from the detailed descri tion to follow. a

We accomplish the o jects of our invention b thedevices and means described in the fo lowing specification.

The structure described constitutes one ef-, fective embodiment of ourinvention. Other embodiments could be readily devised by those skilled in the art.

The invention is clearly defined and point ed out in the claims.

,A. structure constitutin an eifective and referred embodiment of the features of our invention is clearly illustrated in the acspecification, in which;

Figure 1 is-an end elevation of a structure embodying the features of our invention, the lower portion of the pedestal bein broken away. Fig. 2 is a detail longitudinal seccompanying drawing, forming a part of this tional elevation taken on a line correspondshaft bein ing ,to the irregular line 2-2 of Fig. 1, the shownin full lines. Fig. 3 is an enlarge detail transverse sections view, taken on a line corresponding to the irregular line 3-3 of Fig. 2. Fig. 4 is an enlarged detail transverse sectional view, taken on a line corresponding to line 44 of Fig. 2.

- Referringto the drawing, we have illus-.

inner annular wall- 8, which is spaced from the outer wall and forms, in connection with the longitudinnl partitions 5, a series of head chambers 9. Inthese head chambers.) are piston lieads-t), the piston heads bein slidably fitted into the chambers to be adjusted therein and thus to re llhf the length of the suction surface of tie roll. The wall 8 1:

projects beyond the ends of the pertitionsii 5, as clearly appearsin Fig. 2, as does also Betweentthis inner wall18.

hub of the roll, and, with the ends of the partitions 5, present bearing surfaces for The suction header is adjustably supported by'means of the yoke like bracket 14, having a curved slot 15 therein through which the clamping bolts 16 are arranged.

The header is connected to the supporting bracket 14 by means of the pins 17 on the header, which slidably engage the adjustable sockets 18, which are screw-threaded through the support. Between the ends of these sockets l8 and the header we arrange the spiral springs 19, which hold the header yieldingly against its bearings so that, as the suction roll revolves, the compartments are successively brought into connection with the header. A suitable port in the header provides for this connection.

To adjust the heads 9 in the head chambers, we provide them with rods 20, having laterally-projecting pins 21 thereon, which project through the longitudinal guiding slots 22 in the outer wall of the roll, (see Figs. 2 and The adjusting member 2?) is provided with a cam groove 24;, expanded at its forward end to engage these projections as the roll is revolved, and to bring them into alinement. This cam may engage any projecting member connected to said heads. The adjusting member is shifted laterally by means of the screw 25, secured thereto, which is engaged by the nut :26 bearing the hand wheel 27, journ'aied on the bracket 14. The adjusting member 23 is curved to correspond to the curvature of the roll,-see Fig. 3,and is suitably guided longitudinally by the rods 28. By this simple device, the heads 9 may be adjusted in or out uniformly by the manipulation of a single adjusting member, the adjustment being rapid and eas and while the roll is in motion. This ad usting member is of sufficient length to engagerall the head connections that are acted upon by the suction at any particular instant.

In Figs. 8 and 9 we show a modified structure in which the wall 8 is extended andprovided with guide grooves 29 for the head rods 28, which are offset at 30 to engage the groove of the member v I We have illustrated and described our improvements in detail in the form in which ,we have embodied them. \Ve are aware, fjhowever, that the structure is capable of considerable variation in. its details without departing from our invention, but as such variations will be readily understood by those skilled in the art to which this invention relates, we have not attempted to describe or illustrate the same in detail herein.

Having thus described our invention,
